Pore orientation in shale governs the fluid transport properties that are key to hydrocarbon production and potential CO<sub>2</sub> sequestration. The present work deals with the detailed study of nano-heterogeneities in shales, across the bedding plane, of varying thermal maturity and total organic carbon content using scanning small-angle...

Understanding the formation of pore space, especially in low porosity shales (as source rocks and as unconventional resources), is critical to the oil and gas industry, since pores control the space available for hydrocarbon and participate in hydrocarbon transport. We examined 87 Ordovician and Silurian mudstone samples collected from four...

In the process of the exploitation of deep oil and gas resources, shale wellbore stability control faces great challenges under complex temperature and pressure conditions. It is difficult to reflect the micro mechanism and process of the action of inorganic salt on shale hydration with the traditional experimental evaluation technology on...

Complete and thorough core cleaning is a critical prerequisite for the precise measurements of most rock's petrophysical parameters. In shale, the oil cleaning process, aimed to remove the volatile hydrocarbons, is often complicated by the requirement for intact solid organic. Evaluation of shale's cleaning methods needs to take structural...

In close-range applications, it is unclear whether optical photogrammetry is capable of accurately reconstructing submillimetre-scale roughness. This paper presents a study of fine-scale rock fracture roughness measurements with a careful assessment of the error. The workflow combines the techniques of structure from motion with focus...

Gas flow in fractured nano-porous shale formations is complicated by a hierarchy of structural features, ranging from nanopores to hydraulic fractures, and by several transport mechanisms that differ from standard viscous flow used in reservoir modeling. The use of accurate simulation techniques that honor the physical complexity of these...

Given the substantial growth of the shale industry over the last decade, understanding flow in confined spaces will play a primordial role in the future of the upstream petroleum sector. Most compositional simulators are designed for standard (unconfined) reservoirs. Additional physical phenomena occurring in confined spaces such as capillary...

We present an experimental method to study time-dependent, CO<sub>2</sub>-induced, local topography changes in mm-sized composite samples, plus results showing heterogeneous swelling of coal and shale on the nano- to micrometer scale. These results were obtained using high resolution interferometry measurements of sample topography, combined...

The potential of shale reservoirs for gas extraction is largely determined by the permeability of the rock. Typical pore diameters in shales range from the μm down to the nm scale. The permeability of shale reservoirs is a function of the interconnectivity between the pore space and the natural fracture network present. We have measured the...

Gas flow in fractured nano-porous shale formations is complicated by a hierarchy of structural features, ranging from nanopores to microseismic and hydraulic fractures, and by several transport mechanisms that differ from standard viscous flow used in reservoir modelling. In small pores, self-diffusion becomes more important than advection, also...

Geo-resources play an increasing significant role in achieving a sustainable energy future. However, their exploitation is not free of environmental impacts. This paper aims to identify the lessons and knowledge gaps on understanding of the sources, mechanisms and scope of environmental consequences of underground geo-energy resources...

Hydrocarbon reservoirs are currently declining. Reservoirs are becoming depleted, and production needs to satisfy the demand and supply of hydrocarbons. For tight reservoirs such as shales, fracturing will become the main source of improving the permeability. It is therefore vital to conduct research into the behavior of fractures in the...

The rise of shale gas production, has been the greatest revolution in the U.S. energy landscape since WWII and it is argued that market governance facilitated the process. This study analyses the feasibility of EU shale gas development. The publicly available shale gas analyses are inconclusive about the impact of future market design on shale...

While the shale revolution was largely a US’ affair, it affects the global energy system. In this paper, we look at the effects of this spectacular increase in natural gas, and oil, extraction capacity can have on the mix of primary energy sources, on energy prices, and through that on internal political stability of rentier states. We use...

Few people disagree on the need for sustainable development, but ideas about what it exactly means and how to pursue it diverge considerably. Although such normative conflicts are key to sustainability transitions, attention to such conflicts is lacking in transition studies. In this paper we understand societal conflict as an informal...

In this study seismic wave velocity and seismic wave attenuation in dry Bentheimer sandstone, Indiana limestone, and Whitby shale are studied while continuously deforming and therefore increasingly fracturing the rock samples up until macroscopic failure. A pulse transmission technique at a central frequency of 1 MHz is used in combination with...

The introduction of new energy technologies may lead to public resistance and contestation. It is often argued that this phenomenon is caused by an inadequate inclusion of relevant public values in the design of technology. In this paper we examine the applicability of the value sensitive design (VSD) approach. While VSD was primarily introduced...

Gas has proved to be a successful extractable hydrocarbon resource from shale in the United States. In Europe results have so far been disappointing, but with increasing global energy demand a lot of interest remains in the potential of recoverable shale gas reservoirs. However, the way how the economic potential of shale is mapped is...

This thesis consists of multiple approaches to develop a new model to determine the porosity, permeability and the rate of desorption of 1.5-inch shale samples. The raw NMR signal of the sample in the coreholder is measured before methane injection and is used as base signal. During the injection of methane the raw NMR signal increases. The base...
